organized on very much the same plan, and are confined to a very 
limited space or group of islands on the earth’s surface. 
With this animal Mr. Wallace has sent 
1, CyNOPITHECUS NIGRESCENS. 
Papio nigrescens, Temm. Consp. &e. iii. 111. 
Three specimens (with their skulls), two adult and one young. 
The adult agrees well with the specimen which the British Mu- 
seum received from the Leyden Museum as coming from Celebes. 
The younger specimen wants the pale subterminal ring on the longer 
hairs of the shoulder, which are more or less distinctly marked in 
all the adult specimens I have examined. This species is very nearly 
allied to the C. niger of the Philippines. 
Mr. Wallace, in a note, remarks, “These apes are very rare and, 
I think, very interesting, as I expect they are from the most 
southern limits for these animals.” 
I think there must be some mistake in this, because, first, they are 
more Monkeys than Apes; and secondly, both Monkeys and Apes 
are found abundantly in Sumatra and Java, much further southwards 
than Batchian, which is nearly on the equator. ‘ 
The Bats seem numerous on the island, as the collection contained 
fifty-nine specimens. I have not ventured to name or describe them, 
as Mr. Robert Tomes has now taken up this group of animals, and 
promised to form a catalogue of them ; so I leave their determination 
to him. 
2. RHINOLOPHUS, no. 1. 
3. RHINOLOPHUS, no. 2. 
4. RuINOLOpPHws, no. 3. 
These species differ greatly in size and colouring. 
5. HiprosipERos, no. l. 
6. HipposipERos, no. 2. 
The second species is the smallest of the group I have yet seen. 
7. MINIOPTERIS AUSTRALIS. 
Peculiar for the great length of the tail and infemoral membrane, 
and for the length and freedom of the hind feet. 
8. Preropus, no. 1. (Seven specimens. ) 
9. Preropus, no. 2. (Five specimens.) 
10. Preropus, no. 3. A single specimen, of a uniform reddish- 
brown, rather paler on the head. 
These species differ greatly in colour, aud they appear to be very 
uniform, as there are many specimens of nos. 1 and 2, and the indi- 
viduals are much alike.
